Re: Exchange ADSL2+ enabled, can I get it?

On the old "ADSL Max" DLM that you are on that is true, but on the new DLM that runs on BT ADSL2+ it isn't. That will start at 6dB but adjust down to 3dB itself if the line is stable. ADSL2+ is though inherently less stable than ADSL or ADSL2.

As MrSaffron says, I would let it sort itself out for a bit before tweaking.

If you can post the line stats as they are now, so we have a reference point, and then when you are on ADSL2+, we will be able to see if ADSL2 is likely to be the best of the three protocols.
